A reptile's body temperature changes according to Newton's law of heating: \(T(t)=T_{\text{env}}-(T_{\text{env}}-T_{0})e^{-kt}\). The animal's initial body temperature is \(T_{0}=20^{\circ}\)C, the ambient temperature is \(T_{\text{env}}=30^{\circ}\)C and the cooling constant is \(k=0.1\) min\(^{-1}\). How many minutes are required for the body temperature to reach \(28^{\circ}\)C? Give your answer to one decimal place.
